1c42e6334e [text] Emit ::cursor-event only on changes
The documentation for the ::cursor-event says that the signal
is emitted only when the cursor position changes. Right now it
is being emitted every time we ensure the cursor position during
the Text paint sequence.

The clutter_text_ensure_cursor_position() function should check
whether the stored cursor position has changed since the last
paint, and emit the ::cursor-event signal only when there has
been a change.

5c8263ecb7 [text] Limit the Layout width
We only want to eschew the pango_layout_set_width() on editable,
single-line Text actors because they can "scroll" the PangoLayout.

This fixes the ellipsization on entries.

e4d3b0536f [gl/cogl.c] #include <gmodule.h> for OS X builds
In unifying the {gl,gles}/cogl.c code recently, moving most of the code into
common/cogl.c the gmodule.h include was also mistakenly moved.

Thanks to Felix Rabe for reporting this issue.

Note: I haven't tested this fix myself, as I'm not set up to be able to
build for OS X

46c20f1523 [cogl vertex buffers] Adds fallbacks for drivers without VBO support

ac21e7b182 [cogl debug] --cogl-debug=rectangles now outlines all cogl rectangles
This makes the #if 0'd debug code that was in _cogl_journal_flush_quad_batch
- which we have repeatedly found usefull for debugging various geometry
issues in Clutter apps - a runtime debug option.

The outline colors rotate in order from red to green to blue which can also
help confirm the order that your geometry really drawn.

The outlines are not affected by the current material state, so if you e.g.
have a blending bug where geometry mysteriously disappears this can confirm
if the underlying rectangles are actually being emitted but blending is
causing them to be invisible.

fbd9c59c7c [clutter-text] Fix ellipsizing
Ellipsizing was effectively broken for two reasons. There was a typo
in the code to set the width so it always ended up being some massive
value. If no height should be set on the layout it was being set to
G_MAXINT. Setting a height greater than 0 enables wrapping which so
ellipsizing is not performed. It should be left at the default of -1
instead.

a9f24351e9 Fix fullscreening when the stage is unrealized and on dual-head
If the stage is unrealized (such as will be the case if the stage was
created with clutter_stage_new) then it would set the size of the
stage display but it was not setting the fullscreen_on_map flag so it
never got the _NET_WM_STATE_FULLSCREEN property. Now it always sets
the flag regardless of whether the window is created yet.

There was also problems with dual-headed displays because in that case
DisplayWidth/Height will return the size of the combined display but
Metacity (and presumably other WMs) will sensibly try fit the window
to only one of the monitors. However we were setting the size hints so
that the minimum size is that of the combined display. Metacity tries
to honour this by setting the minimum size but then it no longer
positions the window at the top left of the screen.

The patch makes it avoid setting the minimum size when the stage is
fullscreen by checking the fullscreen_on_map flag. This also means we
can remove the static was_resizable flag which would presumably have
caused problems for multi-stage.

fff5585b5f [cogl-pango-render] Fix returning to default color after a color attribute
Since the Cogl material branch merge when changing the color of a part
using pango attributes (such as using <span color="red" /> markup)
then it wouldn't return to the default color for the rest of the
layout. pango_renderer_get_color returns NULL if there is no color
override in which case it needs to revert to the color specified as
the argument to cogl_pango_render_layout. The 'color' member of
CoglPangoRenderer has been reinstated to store that default color and
now cogl_pango_render_set_color_for_part is the only place that sets
the material color.

a1cc1f57ac [animation] Do not connect to ::completed multiple times
The clutter_actor_animate*() family of functions should only connect
to the Animation::completed signal once, during the construction of

signal handler will be run multiple times, and will try to unref()

c3d9f0bed4 [cogl-handle] Optimize how we define cogl handles
The cogl_is_* functions were showing up quite high on profiles due to
iterating through arrays of cogl handles.

This does away with all the handle arrays and implements a simple struct
inheritance scheme. All cogl objects now add a CoglHandleObject _parent;
member to their main structures. The base object includes 2 members a.t.m; a
ref_count, and a klass pointer. The klass in turn gives you a type and
virtual function for freeing objects of that type.

Each handle type has a _cogl_##handle_type##_get_type () function
automatically defined which returns a GQuark of the handle type, so now
implementing the cogl_is_* funcs is just a case of comparing with
obj->klass->type.

Another outcome of the re-work is that cogl_handle_{ref,unref} are also much
more efficient, and no longer need extending for each handle type added to
cogl. The cogl_##handle_type##_{ref,unref} functions are now deprecated and
are no longer used internally to Clutter or Cogl. Potentially we can remove
them completely before 1.0.

04ebd6be44 [cogl] handle_automatic_blend_enable(): consider layers with invalid textures
A layer object may be instantiated when setting a combine mode, but before a
texture is associated. (e.g. this is done by the pango renderer) if this is the
case we shouldn't call cogl_texture_get_format() with an invalid cogl handle.

This patch skips over layers without a texture handle when determining if any
textures have an alpha channel.

a362a4a889 [text] Use the base class binding pool
Bug 1518 - [Patch] Widget derivied from ClutterText will crash on
           key_press_event

In clutter_text_key_press() we are using G_OBJECT_TYPE_NAME to find
out the actor's type name. However, if some widget is derived from
ClutterText, when the key press handler is called, G_OBJECT_TYPE_NAME
will return the name of the derived widget.

The default implementation should get the binding pool for the base
class.

a1a8193179 [text] Check text length in ::button-press-event
Bug 1529 - Selection bound out of sync with an empty Text actor

When the user clicks on a Text actor the cursor position and the
selection bound are set using bytes_to_offset(); if the Text is
empty, this means placing them both to 0. Setting the selection
bound to 0 means that when the user inserts a character by typing
it into the Text, the selection will be [0,1]; this will select
the first character, which will then be overwritten when typing
a new character.

The Text actor should, instead, check if there are no contents
and set the cursor position and the selection bound to -1.

The clutter_text_set_selection_bound() method should also validate
the value passed, in case it's bigger than the text lenght, or
smaller than -1.

The change from calling glBindTexture to using the material API with
cogl_material_flush_gl_state does not always work because it doesn't
necessarily leave the active texture unit as GL_TEXTURE0. For example,
if the previously rendered texture was multi-layered then the last
thing cogl_material_flush_gl_state will do is select GL_TEXTURE1 just
to disable it.
